Specification of Letters Patent.

Patented July 24, 1906,

Application filed May 9, 1905. Serial No. 259,517.

To all whom it may concern,.-

Be it known that l, NnLs T. HANsoN, a citizen of the United States,residing at Hawarden, in the county of Sioux, State of Iowa, haveinvented certain new and useful lmprovements in Cookers; and l do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to cookers, and has for its object to provide acooker including a plurality of chambers, some of which will be equippedto cook matter by the steaming process, while others will be arrangedfor cooking by means of heated air.

Other objects and advantages will be apparent from the followingdescription, and it will be understood that modifications of thespecific construction shown may be made and any suitable materials maybe used without departing from the spirit of the invention.

ln the drawings forming a portion of this specification, and in whichlike characters of .reference indicate simil ar parts in the severalviews, Figure 1 is a side elevation ofthe present invention. Fig. 2 isan elevation taken oppositely to Fig. 1. Fig. 3 is a top plan view. Fig.4 is a section on line 4 4 of Fig. 1, taken transversely of thesteam-chambers. Fig. 5 is a section on line 5 5 oi Fig. 1, takentransversely of the oven and the stove-section. Fig. 6 is a detail viewshowing the stove-sec tion in top pl an and illustrating the means forholding the cooking utensils in position.

Referring now to the drawings, the present invention comprises a Jframe5, provided with supporting-legs 6. Secured to the frame and dependingtherebelow there is a burner-casing 7, provided with openings in itsbottom, yin which are engaged fuel-supply pipes 8 ,which are connectedwith other Jfuel-pipes 9, which are mounted at their ends upon braces10, extending transversely between the legs 6 at each end ofthe Jframe.

Mounted upon the frame there is a plate 11, having a pair oi openings 12adjacent to one of its ends, these openings being rectangular in shapeand extending longitudinally of the plate, and secured to the plateabove each of these openings there is a steamingchamber, the chambersbeing indicated at 13 and 14. These chambers are provided with bottoms15 and disposed to heat the bottom oi the chambers are burners 16, whichlie within the burner-casing 7. Formed through the bottom of the chamber13 there is an opening 16 in which is fitted the end of a pipe 17, thispipe beingconnected with a coil oi pipe 1S, which at a point opposite tothe pipe 17 is provided with an upwardly-extending discharge-pipe 19,which passes outwardly to the top of the chamber. The chamber isprovided with a suitable door 20. The coil 18 lies below the door, anddisposed within the chamber there is a grating 21 for the reception ofmatter to be cooked.

The chamber 14 is equipped similarly to the chamber 13, except that itis provided with two doors and a single pipe 22, opening through its topand bottom. The doors are provided with suitable fasteners 23 and arearranged to form steam-tight closures when they are in their operativepositions.

ln use water is placed in the chambers, and the burners therebeneath arelighted, the latter heating the water, thus generating sutilcient steamto cook the matter dis posed upon the grating, it being understood thatthe chamber 14 is provided with gratingsv 14',

vsimilar to the grating of the chamber 13.

These chambers are provided with gage* glasses 24 to indicate the amountof water Within the chambers. These chambers 13 and 14 are provided attheir tops with safetyvalves A and B, respectively, the safetyvalve Abeing connected, by means of a pipe 45, with the pipe 19, whichcommunicates with the pipe 22 and with a flue 46, the safety-valve Bbeing connected with the pipe 22 to discharge thereinto by means of apipe C.

Adjacent to the opposite end of the plate 11 from the steaming-chambersthere is an` opening 65, above which there is disposed an oven 66, thelatter having an outwardly-extending ilange 67 at its bottom, which issecured to the plate 11 at the edges of the opening 65. Thesteamingchambers described above are secured to the plate 11 in asimilar manner, these chambers being provided with ilanges 67. Y

The oven 66 consists of an outer casing 68 and an inner receptacle 69,the walls of the latter being spaced from those of the former to form aheat-chaniber 70. At its top the IOO IOR

outer casing is provided with an o ening 71, to which a pipe 72 isconnected. W ich communicates with the flue 46. The plate 1'1 extendsinwardly of the walls of the casing 68, and the portion lying inwardlyof these walls and surrounding the opening is struck down, as shown at73, and the inner receptacle 69 lies with its bottom below the loweredges ofthe walls of the casing 68 and within the inclosure of thisdownwardly-struck pore tion, the-bottom of the receptacle 69 lying inspaced relation to the downwardly-struck port-ion, as shown,to formpassages 74, coml municating with the chamber 70, as mentioned above. Aburner is disposed within the burner-casing beneath the voven to heatthe bot-toni ofthe receptacle 67 and the heat from this burner will alsopass ythrough the passages 74 and the chamber 70 to andl through thelipe 72 to the flue 46, it being understood tliiiat the burner justmentioned is connected with one of the fuel-pi es described above. Theovenis provide with a suitable opening formed through the casing 68,which alines with a similar opening formed through the inner receptacle.A filling-block 75 is disposed between the casing andreceptacle and isprovided with an openalining with those oliV the casing and thereceptacle. The openings are provided lwith a suitable closure 76.

Adjacent to the oven the plate 11 is provided with an opening 77, whichcommunicates with the interior of a casin 78, secured above theopeningeby means o? outwardlyextending iianges, which are secured to theplate. This casing forms a portion of a stovesection 79'. In its to thecasing is provided with openings 8O of circular shape, and at therearward portions of these o enings arcshaped plates 81 are secured to te upper face of the casing and have their inner edges directed upwardlyat an angle to receive the outwardly-extending base-anges 82 of variouscooking utensils therebeneath.

In the drawings a coee-urn 83 is shown in position above one of theopenings 80. To prevent displacement of the cooking utensil from theopening, latches 84 are pivoted to the upper face of the casing formovement into and out of position to extend above the base-flanges 82and when in such position hold the utensils against displacement. In itsforward face the casinor 78 is provided with an opening 85, Whic has asuitable closure 86, provided with fastening means 87. Disposed Withinthe burner-casing and extending upwardly within the casing 78 aresuitable burners 88, one lying beneath each of the openings 80, andthese burners arc connected witl the fuel-supply pipes describedY above.Y

rlhe burner-casing is provided with a plurality of partitions whichseparate the burners of the different cooking-sections, and theburner-casing is provided with a plurality of openings 89, through whichthe burners may be'reached, and these openings are provided withclosures 90.

The stove-section 79 has a passage 91, formed through the rearward wallof its casing 78, and with this opening there is connected a pipe 92,which communicates with the flue 46.
